MACHINE-VISE.

SPECIFICATION forming part of Letters Patent No. 510,293, dated December 5, 1893.

Application filed October 14,1889. l Serial No. 327.027. (No model.)

To all whom ill/.may concern:

Be it known that I, WILLIAM G. RICHARDS, a citizen of the United States, residing at Boston, in the county of Suiolk and State of Massachusetts, have invented a new and useful Machine-vise, of which the following is a specification.

My invention relates to improvements in vises for holding work to be operated upon by ro lathes or other machines, aud the objects of my invention are, first, to provide an apparatus having a wide range as to dimensions and form of workit will hold; second, to combine great strength and rigidity, with ease I5 and rapidity of operation. l attain these objects by the mechanism illustrated in the accompanying drawings forming part of this specification, in which- Figure 1 is a plan of the vise placed upon zo the bed 0f a double end lathe, and Fig. 2 is a sectional elevation of the same, taken on line A, B, Fig. 1.

Similar characters designate like parts in both figures of the drawings.

My improved machine-vise has a series of adjustable jaws and 17, supported on a base or frame and radiating from a common axis, the whole forming an adjustable vise for holding varying sizes and forms of valve- 3o bodies, or other articles which are to be operated upon by lathes or other machine to which the device is applied; the axis of the vise and of the machine with which it is to be used should, of course, coincide approxi- 3 5 mately. The vise may be placed at the end of a machine upon an independenty foundation, or upon the bed of a machine as inthe drawings, or upon the wing bearings hereinafter described, which may be an integral 4o part of the machine-bed.

A saddle is formed of two or more adjust-v able jaws 10 radiating from the axis of the vise, at an inclination to, and below, a horizontal line drawn through said axis, which jaws are supported upon wing bearings 11, placed, preferably, longitudinally parallel to the axis of the vise, and coincident to the plane of inclination of the jaws 10, which they support.c

In the surface of wing bearings 11, T- slots 12 are made longitudinally parallel to axis of the vise. The jaws 10, supported upon the wings, as before stated, radiate fro1n,and at right angles to the axis of the vise and the machine with which it may be used, the preferred inclination being about thirty degrees with relation to a vertical line drawn through the axis of the vise. Formed in the said jaws are vertical slots 13 running nearly their entire length. Clamping-bolts 14 are placed with their heads in the T-slots 12 in the wing and passed upward through slots 13 in jaws 10, where they are secured in place by nuts 16, heavy washers 15 being interposed between said nuts and the jaws, as shown. By loosening the nuts 16, it will be seen, thatthe jaws 10 may be moved in a direction parallel to the axis of the vise or at right angles t0 said axis without departing from lines radiating from the Iaxis of the vise or from the center of the work being operated upon.

To accommodate the jaws to various forms and sizes of work to be operated upon, the arrangement of the jaws, slots and connections are such that, if desired, the jaws may be set at various angles with relation to the axial line of ,the vise.

From the foregoing it will be seen that owing to the diversity of adjustments of the jaws very small pieces varying greatly in form, may be quickly placed upon, and between jaws 10, and that very large pieces may be accommodated with equal facility, thus covering a wide range of work.

To make this device effective, one or more jaws 17, (which may be in the form of ascrew, provided with means for operating the same,) are placed in a radial line with relation to the axis of the vise, above and between jaws 10. Said jaw or jaws 17 are suspended preferably in a vertical plane from,and work in,

one or more transverse girders 18, said girders 18, supported at one end by, and swing- *y ing in a horizontal plane upon, one or more columns 19, placed at one side of the vise.

At the side of the vise opposite column or columns 19, a removable tie-rod, or tie-rods 20, pass from one wing-bearing 11, up to the free, or swinging end of the girder, or girders 1S. The lower end of tie-rod 20 is inserted in a transverse T-slot 21, in wing-bearing 11 and the upperend is extended through the slot 22, in the swinging end of the transverse girder, or girders 18. The column or columns IOO 19, are secured rigidly to one of the wingbearings 11, or in case the vise is placed upon a machine, to the bed of said machine, or to each, as may be convenient. The upper end of column or columns 19, are turned to lit the bearing formed in the anchored end of the gi rder or girders 18, and are enlarged below, to form a collar 23. A loose collar 24:, bearing on a shoulder or column 19 and a threaded nut 25 are placed above the girder or girders 1S. This arrangement provides a strong support for the girder or girders 1S, and permits the girders to be easily swung around in a horizontal plane to admit of the placing and adjustment of work to be operated. upon, without obstruction. In case the vise is used upon a double end lathe as shown in Fig. 1, the face-plates 27 will carry the cutting-tools.

The various parts making up the vise as a whole may be ot any size or material desired.

For convenience and economy in construction, the jaws 10 may be of mild steel and may have a piece of hardened steel 26, with a serrated or toothed work-engaging edge inserted in the bearing end of each; also, the jaw or jaws 17 may have upon the bearing end, a piece of hardened steel29, in the form of an inverted cone, or it may have a Hat, serrated surface, and be made in such a manner that the jaw, or jaws 17 may turn within, or upon it.

The jaw orjaws 17 may be operated with a cam or other device instead of a screw.

I do not desire to limit myself to the exact construction and arrangement of saddle shown in the drawings, nor to the exact number of work-holding jaws therein shown, as the general construction and arrangement might be varied and the number of jaws increased to suit diierent classes and forms of work, without departing from the spirit of my invention.

Having thus described my invention, I claiml. A machine-vise, for use in connection with lathes and other machines, comprising a saddle formed ot' lower jaws, adjustable radially and parallel to the axis of the vise, and upper radially-adjustable jaws supported by, and working in, girders arranged to swingin a horizontal plane about a pivot at one end, as a center, substantially as described.

2. A machine-vise, consisting of a saddle formed of adjustable jaws radiating downwardly from the axis of the vise, and upper radially-adjustable jaws supported by, and working in, girders pivotally-supported upon a column secured to a winged bearing of the saddle, said girders being arranged to swing in a horizontal plane, substantially as de scribed.
